本文介绍HAProxy前端接入机制：bind创建监听FD，accept后连接由工作线程持有；SO_REUSEPORT和cpu-map影响连接分配与CPU局部性；expose-fd是平滑重载取回监听套接字的前提；内容切换在stream规则层执行。接入失败需区分bind、maxconn、reload窗口等问题，而非直接归因于backend或ACL。

本文介绍Envoy中Listener filters与FilterChainMatch如何协同选链：先由listener filters（如TLS Inspector）丰富连接元数据，再按FilterChainMatch规则匹配最具体的链，无匹配则走默认链或关闭连接。选错链会导致TLS握手失败或协议错误，而非典型upstream故障。排障应先检查连接是否被accept、Inspector是否识别TLS/SNI/ALPN，再确认命中链名，最后才查network filters。
